Bicomponent composition

ABSTRACT

The instant disclosure generally relates to a bicomponent composition for coloring mammalian or synthetic keratin fibers, the bicomponent composition comprising first, second, components. The first component includes an organic polymer, the second component includes a pretreatment base compound. One or more of the components includes pigment microparticles. The bicomponent composition combines upon application to treated material such as hair, forms a solid coating thereon and has a substantially long color fastness following development (setting). Methods of using such compositions are also described herein.

BACKGROUND

Treatments to mammalian or synthetic keratin fibers, and their surfaces (integument/nonwoven/textile), are well known in the art. Of particular note are treatments that alter the color appearance of the hair or provide other colored or reflective properties through surface treatment of the hair; dissolution (absorption) of dye molecules into the keratin fiber or attachment to the fiber surface (so called direct dyes); and/or dissolution of dye precursors into the keratin fiber, followed by reaction of these dye precursors within the hair to form dye species (so called oxidative dyeing). Surface coloration treatments and many soluble dyes can be later washed out. Alternatively, pigments can be adhered to the hair surface to alter the perceived color.

One drawback of the known oxidation based technologies in this area is that the methods for applying dye based coloring materials involves compositions that may in some cases cause temporary irritation to the scalp. This prevents the hair coloration experience from being pleasant or a so called wellness experience. Such coloring compositions also alter the hair structure itself, leading to oxidation of the hair surface, and partial degradation to the keratinous proteins from which the hair structure is constructed. With repeated coloring, these changes in hair structure become more pronounced. The color obtained when coloring with such composition is hard to predict, and even highly experienced users can still be surprised with the results that are obtained. Yet another drawback to known technologies is that, once the color is on the hair, the dye based coloring material is difficult to remove and/or cannot be completely removed.

Another drawback for the dye based approach is that the application of hair coloration materials can yields uneven results as adherence to the surface and/or penetration of hair coloration materials into the hair can vary with hair type for example for a consumer differing color results may be visible between hair roots and hair tips. This can lead to an unnatural looking result. Some desired differences may still be visible due to the non-uniformity in coloration of the underlying hair, for example subtle difference in strand to strand levels of pheomelanin and eumelanin in a consumer may yield slightly different color results, even when the same color pigments or dyes are applied to a consumer. While some strand to strand variation is needed to provide natural looking hair, too much or too little can again lead to an unnatural looking color result. Due to the number of factors that determine the final hair color result for example, the length of application time, the underlying hair color, the hair changes from root to tip, it is difficult even for experienced users to accurately predict the final color result and look.

A drawback of pigment based coloring approaches is the low adherent fastness of the pigment or colored material to the keratin fibers. While the low adherent fastness or remanence has been attributed to the use of film formers that are water soluble, substituting film formers that are classed as water insoluble does not deliver much better remanence. Irrespective of the film former applied, the result is effective removal of the color on the hair after only a few washings with shampoo. Especially for persons who shampoo daily, the rapid color loss creates an undesirable situation.

Another drawback for both dye and pigment based approaches is that the application of hair coloration materials often yields uneven results as (1) adherence and or penetration of hair coloration materials to the hair surface or within the hair can vary with hair type for example due to changes in porosity, changes in surface composition due to proximity to scalp and/or age of the user; and (2) even when material is adhered or penetrated into the hair, differences in coloration of the underlying hair, including presence of pheomelanin and eumelanin, may yield different color results, even when the same color pigments or dyes are applied across hair types/colors having different native characteristics.

There is therefore a need for an improved composition and method that not only make the hair coloring experience more pleasant, but also is user friendly, provides appropriate color and luster, and leaves the hair manageable, free flowing and capable of moving naturally and does not result in harm to hair protein.

SUMMARY

According to aspects of the invention, embodiments of the bicomponent composition for coloring treated material, methods for its production and application, coated treated material resulting from the bicomponent composition and methods for removal of the coating provide a surface coloration of keratin material and textiles, especially hair, that may be substantially uniform to significantly varied, may give such material an appearance of a lower or higher chroma, shiny or reflective nature. [Hereinafter the combination of keratin materials and textiles will be designated as treated material.] These aspects provide color fastness during a series of washes with shampoo or soap yet with appropriate formulations can be readily removed to leave the natural state of the treated material and especially the natural state and/or shade of the hair when hair is the kind of treated material used. These aspects significantly lessen and/or avoid treatment of treated material that may cause breakage of keratin protein intermolecular bonds and interruption of mechanical and/or chemical linkages of textiles.

It has been discovered that application of embodiments of the bicomponent composition comprising first and second components to treated material delivers significantly increased remanence. The first and second components with constituents including respectively an organic polymer and a pretreatment base compound combine to provide remanence, flexibility, softness and similar properties to the resulting coating. The combination of the pretreatment followed by application of the first component achieves a coating on the treated material with remarkable remanence.

One aspect of the invention concerns a bicomponent composition. Embodiments of the bicomponent composition comprise a first component comprising an organic polymer, a second component comprising a pretreatment base compound. The first and second components are capable of forming dipolar and/or electrostatic interaction with each other as well as with the treated material

The bicomponent composition also comprises a medium with one or more of the first and second components and pigment microparticles incorporated into one or more of the first and second components.

The first and second components are typically maintained separately. If multiple, different functional groups are present in either, or both, of the first and second components, the multiple different functional groups are selected to be appropriately compatible. For example, the presence of multiple different functional groups of the organic polymer are selected or adapted or otherwise controlled so that they do not interact together while standing alone and separate from the pretreatment base compound.

The first and second components of the bicomponent composition may be applied separately and sequentially to the treated material. Upon the combination of the first and second components, the organic polymer and the pretreatment base compound interact to form a wash resistant coating with pigment microparticles on the treated material. While it is not a limitation of the invention, it is believed that the base compound enables interaction among the organic polymer, the pretreatment base compound and the treated material. This interaction is believed to adhere substances together to make them resistant to removal by ordinary means.

The embodiments of the first component include an organic polymer respectively of the pretreatment base compound and the base compound in a manner as described above. The organic polymer may be any carbon based polymer based on olefinic monomers, polyol monomers, ester monomers, amide monomers, carbonate monomers, natural occurring monomers and polymers having repeating monomeric residues based on carbon or carbon in combination with other atoms such as oxygen and/or nitrogen, and any combination thereof.

The embodiments of the second component include a base compound. The base compound is composed of a small molecule or an oligomeric or polymeric organic or silicone core to which is covalently bonded pendant or terminal or pendant and terminal amine, carboxylate, sulfonate, carbamate and mercapto groups, preferably amine groups. The is typically and usually adapted to be combined with the treated material as a pretreatment followed by application of the first component. The first and second components are typically maintained in a separate container prior to use.

The molar ratio of pretreatment base compound to organic polymer will depend upon the kinds and numbers of pendant functional groups of the organic polymer, the pretreatment base compound to achieve the desired properties of the coating of the composition. The interaction will improve resistance of the coating toward removal with dilute soap or shampoo aqueous solutions while preserving free hair flow properties and avoid stickiness and clumping.

Embodiments of the pigment microparticles used on the bicomponent composition described herein may comprise organic pigment microparticles, which imparts color to the hair, and colored reflective microparticles, for providing light scattering properties to the colored hair, Embodiments may also include microparticle metal flakes for light reflection to add shine to the desired color or to make the hair appear to be lighter than the starting hair color.

An aspect of the invention concerning the method for coating the bicomponent composition with treated material comprises applying the pretreatment base compound to the treated material and preferably at least partially drying to form pretreated treated material. Next, the first component may be applied to the pretreated treated material. The pretreated treated material coated with the first component may be dried with optional heat to cause formation of a colored coating on the treated material. The embedded pigment microparticles are somewhat to substantially uniformly distributed in and throughout the coating.

In addition to the organic polymer, pretreatment base compound and pigment microparticles of the first and second components, the bicomponent composition may optionally contain additional ingredients helpful and beneficial to the treated material and/or its coloration. These additional ingredients include but not limited to one or more of dispersants, surface treatment agents for the pigment microparticles, plasticizers, conditioners, suspending agents, thickening agents, adjuvants, moisturizers, surfactants, fatty substances, hair feel modification agents, waxes, fatty amides and soluble organic dyes of colors different from those of the pigment microparticles.

An aspect of the invention concerning the fastness or remanence of the coating on the treated material, and especially on hair strands, comprises the ability of the coating to somewhat to substantially resist dissolution by ordinary cleaning of the treated material such as hair. Ordinary cleaning may involve washing with soap and water, washing with an aqueous dilution of shampoo and washing with water.

An aspect of the invention concerning removal of the coating on the treated material, such as on hair strands, comprises application of a trigger formulation designed to remove the coating. The trigger formulation embodiments of the invention may comprise a medium with a base. Embodiments of the base include organic and inorganic compounds that provide a stronger basic medium than does a dilute aqueous mixture of soap or a shampoo containing an anionic surfactant.

An additional aspect of the invention concerns the application of the bicomponent composition to treated material such as brows, lashes, nails and skin as well as to hair on the scalp. Additionally, the bicomponent composition may be applied to textiles made of plant material, animal hair or fur or synthetic material. The bicomponent composition may be applied to these kinds of treated materials and to textiles with appropriate adjustments of the composition parameters within the parameters described for hair on the scalp. Typically, the eyebrow hair may be treated with the bicomponent composition using parameters similar to or the same as those of the bicomponent composition for hair on the scalp. The hair of eyelashes typically can be similarly treated with the bicomponent composition for eyebrows and the viscosity adjusted to provide a somewhat more viscous composition for application to the eye lashes. For nails and skin, the parameters of the bicomponent composition may have a higher solids content and higher number of first and second components third functional groups for combining than the parameters for the hair and viscosity may be adjusted to provide embodiments that will not readily drip or otherwise flow off the nail or skin surface to which the bicomponent composition is applied. The bicomponent composition for nails and textiles will preferably have higher interaction to provide a durable coating or covering on the keratin nail and textiles.

The suffix “ate” means that the term (meth)acrylate is an ester formed by combination of a monoalcohol or diol with methacrylic acid or acrylic acid.

Acid value is determined by the usual and customary method described in chemical literature.

The molecular weight of a polymer or oligomer used according to the invention may be measured by a weight average molecular weight, and the distribution of molecules of different molecular weights of a polymer or oligomer used according to the invention is determined by its polydispersity index. Molecular weight is expressed as Daltons (Da), kilo Daltons (KDa) and mega Daltons, which is million Daltons or (MDa). The acronym M_(w) stands for weight average molecular weight and M_(n) is the number average molecular weight of a given polymer. Polydispersity is a unit-less number and indicates the breadth of the distribution of the polymer molecular weights and is defined as the W_(m)/M_(n).

The term “about” is understood to mean±10 percent of the recited number, numbers or range of numbers.

The term “about 0 wt. %” is understood to mean that no substance, compound or material to which zero (0) refers is present, up to a negligible but detectable amount is present, assuming that the detectability can be determined on a parts per million basis.

The term “hydrogen bonding” is understood to mean a compound or group that contain a hydroxyl group or a hydrogen that is part of a polar group, such as but not limited to an amine, a carboxylic acid, a urethane group, a urea group and other similar groups and that can form molecule to molecule interaction through electrostatic or ionic interaction between positive and negative dipolar or ionic groups.

Where features or aspects of the invention are described in terms of Markush groups, those skilled in the art will recognize that the invention is also thereby described in terms of any individual member or subgroup of members of the Markush group. For example, if X is described as selected from the group consisting of methyl, ethyl or propyl, claims for X being methyl and claims for X being ethyl and propyl are fully described. Moreover, where features or aspects of the invention are described in terms of Markush groups, those skilled in the art will recognize that the invention is also thereby described in terms of any combination of individual members or subgroups of members of Markush groups. Thus, for example, if X is described as selected from the group consisting of bromine, chlorine, and iodine, and Y is described as selected from the group consisting of methyl, ethyl, and propyl, claims for X being bromine and Y being methyl are fully described.

If a value of a variable that is necessarily an integer, e.g., the number of carbon atoms in an alkyl group or the number of substituents on a ring, is described as a range, e.g., 0-4, what is meant is that the value can be any integer between 0 and 4 inclusive, i.e., 0, 1, 2, 3, or 4. Similarly, values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range were explicitly recited. For example, a range of “about 0.1% to about 5%” or “about 0.1% to 5%” should be interpreted to include not just about 0.1% to about 5%, but also the individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the indicated range.

Hair and hair strands mean natural or synthetic keratin fibers. Hair, hair strands and keratin fibers are used interchangeably in this document. Natural keratin fibers include those from mammals and/or on mammals including human, primate, ruminant, camelid, equine, rodent and neovison including but not limited to cow, sheep, deer, goat, buffalo, lama, alpaca, camel, guanaco, vicuna, horse, antelope, moose, elk, rat, mouse, beaver, rabbit, mink, monkey, ape and similar species. Natural keratin fibers may include hair, fur or nails. Synthetic fibers include polyamides, polyacrylic and polyester fibers, especially polyamide fibers which are used for artificial hair implantation.

Oligomer and polymeric compounds mean repeating units of carbon-carbon backbones with side chains of various classes of groups. The oligomeric and polymer compounds may have side chains of aliphatic groups such as alkyl and/or alkenyl groups, aromatic groups such as phenyl and/or naphthyl groups, heteroaromatic groups such as pyridinyl, quinolinyl, quinazolinyl groups, carboxylic acid groups, hydroxyl groups, amine groups, mercapto groups, sulfo acid groups, sulfinyl acid groups, carboxyl ester groups, carbamide groups, sulfamide groups, alkoxy groups, monomeric, oligomeric and/or polymeric ether groups, monomeric, oligomeric and/or polymeric imino groups, and optionally may have some reactive derivative groups such as an acyl group bound to a leaving group. The oligomeric and polymeric compounds may be composed of a single monomeric unit structure such as polystyrene or polyacrylic acid or may have several different monomeric unit structures such as poly (styrene-acrylic acid-methyl acrylate). The multiple monomeric unit structures may include side chains of esters, amides and side chains such as alkyl groups or aromatic groups or similar groups which not derived from carboxylic acid groups.

As used herein, the term “transfer resistance” generally refers to the quality exhibited by compositions that are not readily removed by contact with another material, such as, for example, an item of clothing or the skin. Transfer resistance can be evaluated by any method known in the art for evaluating such. For example, transfer resistance of a composition can be evaluated by the amount of product transferred from a wearer to any other substrate after the expiration of a certain amount of time following application of the composition to the hair. The amount of composition transferred to the substrate can then be evaluated and compared. For example, a composition can be transfer resistant if a majority of the product is left on the wearer's hair. Preferably little or no composition is transferred to the substrate from the hair.

A transfer test method means the ability or lack of ability to transfer color from treated material to clothing or other material. The transfer of the composition from the hair can be assessed using the following method. Hair tresses are colored according to the test method described. A white cotton cloth is used to test the composition transfer. The cloth measuring 15 mm by 75 mm is folded in half so as to create two sides with a size of 15 mm by 37.5 mm. Between the two sides the colored hair tress is inserted and laid flat onto a surface such that the top portion of the tress where it is glued together just protrudes from the folded two sides of cotton. A weight of 0.1 Kg is applied evenly over the top surface of the cotton and the hair which is wrapped below it. The hair tress is then pulled through the cotton cloth over a time until it is removed altogether from the cloth in 1 to 3 seconds. The weight is removed, and the cloth opened to reveal the inner surface. A visual assessment can then be performed on the sample to give it a rating from 0 to 5 for color transfer, with 0 being no transfer and 5 being extremely high transfer. The method can also be used to compare between different prototypes and provide a comparative assessment of better or worse performance.

As used herein, the term “minimally alters the keratin material or fibers, upon application” generally means that after removal of the composition coating on the keratin fibers such as hair, the keratin fibers are returned to a substantially unaltered state. The state of the keratin fibers such as hair can be assessed for example using ATR FT-IR for oxidative damage as described later or through tensile testing methods known to those skilled in the art for assessing fiber strength for example using equipment such as those designed and sold by Dia-Stron™.

As used herein, the term “setting” means converting the bicomponent composition to a solid coating through the application of means designed to remove or otherwise separate the medium from the other constituents of the bicomponent composition so as to leave a solid coating of the organic polymer, pretreatment base compound and base compound and other optional ingredients of the composition.

“in situ” is a Latin phase meaning in its original place. In the context of this invention, it means an activity such an interaction arrangement by hydrogen bonding, polar coupling or electrostatic activity between two or more molecules that occurs in place on the treated material such as hair.

Bivalent radicals formed from substituted benzene derivatives and having the free valences at ring atoms are named as substituted phenylene radicals. Bivalent radicals derived from univalent polycyclic hydrocarbon radicals whose names end in “-yl” by removal of one hydrogen atom from the carbon atom with the free valence are named by adding “-idene” to the name of the corresponding univalent radical, e.g., a naphthyl group with two points of attachment is termed naphthylidene. The term includes monocyclic or monocyclic-ring polycyclic (i.e., rings which share adjacent pairs of ring atoms) groups.

“Heteroalkyl” “heteroalkenyl” and “heteroalkynyl” include optionally substituted alkyl, alkenyl and alkynyl radicals and which have one or more skeletal chain atoms selected from an atom other than carbon, e.g., oxygen, nitrogen, sulfur, phosphorus or combinations thereof. A numerical range may be given, e.g. C₁-C₄ heteroalkyl which refers to the chain length in total, which in this example is 24 atoms long. For example, a —CH₂OCH₂CH₃ radical is referred to as a “C₄” heteroalkyl, which includes the heteroatom center in the atom chain length description. Connection to the rest of the molecule may be through either a heteroatom or a carbon in the heteroalkyl chain.

Zeta potential relating to pigment microparticles means the electrokinetic potential of extremely small particles suspended in colloidal dispersions. It is caused by the net electrical charge at the particle interface with the suspending fluid. It is an indicator of the stability of a colloidal dispersion. The magnitude indicates the degree of electrostatic repulsion between adjacent similar charged particles in a dispersion. At zero or minimal+ or − potential, rapid coagulation can occur. At a + or − zeta potential above about 40, good colloidal stability is maintained. Zeta potential can be measured using approaches known to those skilled in the art.

DETAILED DESCRIPTION

Aspects of the present invention generally relate to disadvantages of known technologies for coloration of treated material, especially keratin material such as but not limited to hair by limiting damage to keratin proteins within the material, particularly after repeated dying events; facilitating the quantitative or substantially quantitative on demand removal of the color; limiting quick or inconsistent wash-out of the coloring means; limiting the potential for temporary irritation of the scalp upon applying known compositions (e.g., containing hydrogen peroxide at and an elevated pH); and shortening at least one of the treatment process and post-treatment processes, including drying time. In sum, the present invention is directed to compositions for coloration of treated material in such a way that the color can be applied and remain on the treated material until it is desired to remove the color. This makes the treatment process more pleasurable for the user and or stylist. It is also desired that the results are predictable, enabling the user to achieve their target hair color result.

The composition, method and coating aspects of the invention are directed to embodiments of a bicomponent composition that are adapted to provide colored coating embodiments on the surfaces of treated material such as but not limited to hair strands. The colored coating embodiments have “color fastness” or remanence that enables them to remain in somewhat to substantial original composition on the treated material through at least a series of washings with aqueous media containing soap and/or shampoo. Yet by manipulation of the triggering formulation according to the invention, the coating embodiments can be removed from the treated material to leave it in its substantially to essentially natural state before application of the bicomponent composition to the treated material. The bicomponent composition embodiments minimally alter treated material upon their application thereon and the embodiments of the method of application may be accomplished in short times.

The embodiments of the bicomponent composition according to the invention comprise first and second components formulated to provide the desired coloration of treated material, to provide the desired remanence and to provide the ability for removal without damage to the treated material. Sequential application of the first and second components will provide the desired benefits. Pretreatment of the treated material with the second component followed by application of the first component delivers the results for remanence and appropriate quality parameters especially for the treated material. The combination of the two components of the bicomponent composition in the aspect of use and application to treated material provides an unexpected synergy in delivering outstanding properties of remanence and tactile quality for the colored coating on treated material.

The preferred functional groups may be polar and/or protic groups including but not limited to carboxylic acid groups, hydroxyl groups, amine groups, mercapto groups (i.e., thiol, —SH), sulfo acid groups (HO₃S—), sulfino acid groups (HO₂S—), or any combination thereof. Not all organic polymer molecules may bear the same number of functional groups.

The functional groups may be covalently linked to the polymer backbone through any manner of carbon-carbon or carbon-silicon connection arrangements or units. These carbon and/or silicon connection arrangements may be but are not limited to a carbon connection unit comprising a linear, branched or cyclic C1-C24 alkylenyl, oxyalkyenyl, alkylenyloxy or oxyalkylenyloxy unit, a C2-C24 alkanoyl or oxyalkanoyl unit, a C6-C24 aromatic or oxyaromatic unit, a C5-C24 heteroaromatic or oxyheteroaromatic unit having one or two heteroatoms selected from nitrogen, oxygen and sulfur, a (C_(z)—O—C_(z))_(n) polyether unit wherein z is an integer of 1 to 6 and n is an integer of 2 to 6, a (C_(y)—NH—C_(y))_(m) polyimino unit wherein y is an integer of 1 to 6 and m is an integer of 2 to 6.

For example, an alkylenyl group is connected to the polymer chain by a carbon-carbon bond while an oxyalkylenyl group is connected to the polymer chain by a carbon-oxygen bond.

Alternatively the functional groups may be covalently linked to the organic polymer through a linear or branched silicon connection unit comprising a Si1-Si24 organosiloxane moiety (as R₂Si0₂ monomeric residues) having methyl as the organo group with silicon of the connection unit bonded to the functional group through an alkylenyl group of one to three carbons or through an oxyalkylenyl group of one to three carbons or through an oxyalkylenyloxy group of one to three carbons and combinations thereof.

A preferred silicone polymer is one having amine functional groups (hereinafter an aminosilicone polymer). The molar ratio of siloxane monomeric units with at least one pendant organic amine group (hereinafter SiA moieties) to siloxane monomeric units having silicon bonded to a substituent selected from the group consisting of alkyl (C1 to C6) (hereinafter SiC moieties) is in the range of from about 1:1000 to 1:10 (ratio of SiA units to SiC units), preferably 1:1000 to 1:25, more preferably 1:600 to 1:50, most preferably 1:400 to 1:75 or 1:300 to 1:200.

The amine group or groups may be pendant to the silicone chain at uniform or random locations along and within the silicone chain. The amine functional group may also terminate the ends of the silicone chain but an aminosilcone polymer having terminal amine groups preferably will also have pendant amine groups along the silicone chain. If the aminosilicone polymer contains only terminal amine groups, its weight average molecular weight preferably will be low so that its SiA:SiC ratio will conform to the foregoing values.

The base compound is arranged to be applied to the treated material as a pretreatment before application of the first component.

The weight percentage of the organic polymer and the pretreatment base compound is between 1-10 wt. % of the combined first and second components including the medium and pigment.

Viscosity, Composition Concentrations

The viscosity of the composition functions to hold the composition with pigment microparticles in place on the treated material while the coating is formed. The viscosity substantially avoids free translational flow of the composition. Free translation flow would cause the composition to rapidly run and drip off the surfaces of the hair strands. Nevertheless, the viscosity is not so high that it will not undergo self-leveling to substantially uniformly coat the treated material. Appropriate viscosity of the composition is the result of the interaction of the organic polymer, the base compound, their concentrations, the pigment microparticles, and as appropriate, an optional viscosity control agent, an optional suspending agent and an optional thickening agent. Generally, the viscosity of the composition may range from about 0.001 to about 2000 Pa s⁻¹. Viscosity measurements are carried out on a controlled stress rheometer e.g. Using an AR2000 type manufactured by TA Instruments, or equivalent instrument. A 6 cm flat acrylic cross hatched parallel plate geometry (TA item 518600.901) and a stainless steel cross hatched base plate (TA item 570011.001) are used. The rheometer is prepared for flow measurements as per standard manufacturer procedure. The parallel plate geometry gap is set to 1000 microns. The flow procedure is programmed to the rheometer with the following conditions: continuous stress ramp 0.1-300 Pa over 2 minutes at 25° C., including 250 measurement points in linear mode. The product is loaded into the geometry as per standard procedure and the measurement commences at 5 min after the mixture preparation. Shear stress value at 10 sec⁻¹ shear rate is obtained from the shear stress vs. shear rate curve, and the corresponding viscosity is calculated by dividing the obtained shear stress by 10.

The concentration of the organic polymer in the composition may range from about 2% to about 30%, preferably about 4% to about 25%, more preferably about 6% to about 20%, most preferably about 8% to about 15% by weight relative to the total weight of the composition. Specific concentrations include about 2%, about 4%, about 6%, about 8%, about 10%, about 12%, about 14%, about 16%, about 18%, about 20%, about 22% about 24% by weight relative to the total weight of the composition. The determination of the concentration for embodiments of the organic polymer and pretreatment base compound will depend in part upon the resulting viscosity, the saturation point of the organic polymer in the medium. As discussed above, the viscosity is managed so that the composition will not run off the surfaces of strands of hair yet will level and flow to substantially coat those surfaces. Development of appropriate viscosity in part by management of the concentration of the organic polymer can be experimentally determined by routine methods such as formulation of several samples of differing concentrations of polymer in the composition, coating those samples on a hair tress and observing the flow, spread and leveling of the composition on the hair strands. The product can be applied to a treated material such as a hair tress using the coloring procedure described herein afterwards. The top of the hair strand, where it is glued together is clamped in a stand such that the hair is aligned vertically downwards. After a 5 minute dwell time it is observed if any and how much product has dripped from the hair tress. The results obtained from the several samples can be plotted against flow time and leveling time to determine an appropriate concentration or range of concentrations of the organic polymer in the composition.

The glass transition temperatures of the organic polymer and the pretreatment base compound in part contribute to the flexibility, strength, hardness and similar qualities of the coating on the treated material surfaces. The glass transition temperature of these embodiments may range in degrees Celsius from about −125° C. to about 90° C. This glass transition temperature or T_(g) determines the solid-solid transition of the polymer from a hard glassy material to a soft rubbery material. If the T_(g) of the polymer is too high, the coating on the treated material will be stiff and inflexible. This is an undesirable result. The coating should be soft, flexible and unnoticeable to touch and sight yet should not flake, break-up or otherwise release from the keratin fiber, and especially from human hair, when stroked by a hand or brushed with a brush. The Tg of a polymer can be measured using ASTM D7426-08 (2008).

According to an embodiment, the medium is an aqueous medium.

D. Pigments

The color composition embodiments of the present invention make it possible to obtain colored and remnant coatings, without substantially altering the keratin fibers. As used herein, the term “pigment” generally refers to any particle colorant having or containing pigment material that gives hair fibers color including black and white, such as titanium dioxide that give only white to hair fibers. The pigments are substantially water-insoluble. The pigments, to distinguish from dyes presented in molecular from, are also referred to as pigment microparticles or pigment particles. The terms pigment microparticles and pigment particles are synonymous and are used herein interchangeably. The pigments can be organic, inorganic, or a combination of both. The pigments may be in pure form or coated, for example with a polymer or a dispersant.

Selections, multiple kinds and varying forms of the pigment microparticles as described in the following passages can be incorporated in any of the first and second components of the bicomponent composition, or can be incorporated in any two of these components or in all three. Preferably, pigment microparticles can be incorporated in either or both of the first and second components. More preferably, pigment particles can be incorporated in the first component.

The at least one pigment that can be used can be chosen from the organic and/or mineral pigments known in the art, such as those described in Kirk-Othmer's Encyclopedia of Chemical Technology and in Ullmann's Encyclopedia of Industrial Chemistry. The pigments comprised in the microparticles comprising at least one pigment will not substantially diffuse or dissolve into keratin fibers. Instead, the pigment comprised in the microparticles comprising at least one pigment will substantially remain separate from but attached to the keratin fibers.

The at least one pigment can be in the form of powder or of pigmentary paste. It can be coated or uncoated. The at least one pigment can be chosen, for example, from mineral pigments, organic pigments, elemental metal and their oxides, and other metal modifications, lakes, pigments with special effects such as nacres or glitter flakes, and mixtures thereof.

Pigment Shape

The pigment microparticles can have any suitable shape, including substantially spherical. But the pigment microparticles can also be oval, elliptical, tubular, irregular, etc., or even combinations of various shapes. In addition, the pigment microparticles can have two dimensions, length and width/diameter, of similar magnitude. In addition, the pigment microparticles can be micro platelets, i.e. having a thickness that is substantially smaller than the planar dimension. For example, five, ten or even 20 times smaller in thickness than in the planer dimension. In one embodiment with any of the reactive components of the instant invention, the pigments may be surface treated, surface coated or encapsulated.

In a particular aspect, the pigment microparticles can have a shape approximating that of a sphere, in which case the microparticles are referred to as being microspheres. Pigment microparticles which can be described as microspheres are understood as particles having an aspect ratio, defined as a function of the largest diameter, or largest dimension, dmax and the smallest diameter, or smallest dimension, dmin, which can be orthogonal to each other: AR=dmax/dmin which is from about 1:1 to 10:1, preferably from 1:1 to 5:1, more preferably from 1:1 to 4:1, such as from 1:1 to 3:1. More particularly, the expression “spherical-type” means that the pigment microparticles have a shape approximating that of a sphere. In other words, the pigment microparticles can be nearly orbicular in shape and can have a cross-sectional geometry that is essentially circular. Although not excluded, this does not necessarily mean that the pigment microparticles have the shape of a perfect sphere or ball. More likely, the shape of the pigment microparticles can exhibit a certain deviation from a sphere as long as the skilled person considers the shape as being similar to a sphere or as an approximation of a sphere.

In addition, the pigment microparticles can have a rather two-dimensional shape, with the smallest dimension substantially smaller than the two other dimensions, in which case the microparticles are referred to as being 2-dimensional microparticles. For example, the thickness of the microparticles can be significantly less than their length and width. The length and width can be of similar magnitude. Examples includes pigment microparticles having a shape of platelets, i.e. with a thickness that is substantially smaller than the planar dimension. For example, the aspect ratio AR=dmax/dmin, as defined above, of microparticles having a substantially two-dimensional shape, can be from about 10:1 to about 1000:1, preferably from about 10:1 to about 800:1, preferably from about 20:1 to about 800:1, preferably from about 10:1 to about 600:1, preferably from about 20:1 to about 600:1. Typically, the 2D-microparticles have a largest and a smallest dimension in their planer dimension, which both are significantly larger than the smallest dimension of the 2D-microparticles extending perpendicular to the planer dimension.

According to an embodiment, the pigments can include pigment microparticles of different shape. For example, microparticles of different size can be used to provide different reflecting and absorbing properties. Microparticles having different shape can also be formed of different pigment material. Furthermore, microparticles having different shape can also formed of different pigment material to provide different color.

Pigment Size

The pigments can be present in the composition in undissolved form. Depending on the shape, the pigments can have a D50[vol] particle diameter of from 0.001 micron to 1 micron.

For example, pigments that can be described as being microspheres can have a D50[vol] particle diameter of from 0.01 micron to 1 micron, preferably of from 0.015 micron to 0.75 micron, more preferably of from 0.02 micron to 0.50 micron. The microspheres can also have a D50[vol] particle diameter of from 0.6 micron to 0.9 micron, preferably of from 0.08 micron to 0.9 micron, and more preferably between of from 0.08 micron to 0.9 micron, such as from 0.08 micron to 0.8 micron, or such as of from 0.8 micron to 0.6 micron. According to an embodiment, the microspheres can also have a D50[vol] particle diameter of from 0.1 micron to 1 micron, preferably of from 0.12 micron to 1 micron, and more preferably between of from 0.16 micron to 1 micron, such as of from 0.2 micron to 1 micron, or such as of from 0.08 micron to 0.4 micron. The terms “micron” and “microns” describe the size in micrometers [μm].

In further embodiments, which can be combined with other embodiments described herein, the pigments, which can be described as microspheres, can have a D90[vol] particle diameter of from 0.1 micron to 1 micron, preferably of from 0.2 micron to 1 micron, and more preferably between of from 0.3 micron to 1 micron, such as of from 0.3 micron to 0.9 micron, or such as of from 0.4 micron to 0.8 micron, or such as of from 0.5 micron to 0.9 micron.

In some embodiments described herein, the pigments, which can be described as microspheres, can have a D10[vol] particle diameter of from 0.02 micron to 0.3 micron, preferably of from 0.06 micron to 0.3 micron, more preferably of from 0.08 micron to 0.3 micron, such as of from 0.08 micron to 0.2 micron, or such as of from 0.1 micron to 0.2 micron, or such as 0.12 micron to 0.3 micron.

In embodiments described herein, the D10[vol] particle diameter can be of from 0.02 micron to 0.3 micron and the D90[vol] can be of from 0.3 micron to 1 micron. In further embodiments, the D10[vol] particle diameter can be of from 0.06 micron to 0.2 micron and the D90[vol] can be of from 0.4 micron to 1 micron.

The particle diameter is represented by D10, D50 and/or by D90, which is the median diameter by volume. D10, D50 and D90 is measured with a Malvern Mastersizer 2000, which is a laser diffraction particle sizer and it is measured according to ISO 13320:2009(en) with Hydro 2000G or Hydro 2000S where the dispersant is water or ethanol. Detection range is from 0.01 micron to 2000 micron. D50 is expressed as ×50 in ISO 13320:2009(en).

The term “D10,” as used herein refers, to the 10th percentile number- or volume-based median particle diameter, which is the diameter below which 10% by number or volume of the particle population is found. The term “D50,” as used herein refers, to the 50th percentile number- or volume-based median particle diameter, which is the diameter below which 50% by number or volume of the particle population is found. The term “D90,” as used herein refers, to the 90th percentile number- or volume-based median particle diameter, which is the diameter below which 90% by number or volume of the particle population is found. The number or volume measurement is indicated by [num] for number or [vol] for volume. If not indicated otherwise, the particle size is given as D10[vol], D50[vol], and D90[vol], respectively.

Laser diffraction measures particle size distributions by measuring the angular variation in intensity of light scattered as a laser beam passes through a dispersed particulate sample analyzer and the particle size is reported as a volume equivalent sphere diameter. A discussion of calculating D50 is provided in Barber et al, Pharmaceutical Development and Technology, 3(2), 153-161 (1998), which is incorporated herein by reference. Pigment microparticles having a D50[vol] particle diameter of less than 20 nm may enter the cuticles and are therefore difficult to remove. For scattering purposes, Pigment(s) having a D10[vol] particle diameter of at least 60 nm, or at least 80 nm can be used. Pigment(s) having a D50[vol] particle diameter of more than 1 micron typically do not sufficiently adhere onto hair fibers.

According to an embodiment, the particle size distribution, either relative to the number or volume of the particles, of the pigment microparticles can be at least bi-modal. A bi-modal particle size distribution has two distinct peaks which are spaced relative from, while tri-modal particle size distribution has three distinct peaks. The term “peak” means a local maximum of the distribution curve. The “distance” between two peaks, expressed relative to the particle size, can be at least 0.05 micron, preferably at least 0.1 micron, such as at least 0.2 micron. Providing an at least bi-modal particle size distribution allows to tailor the optical appearance of the colored hair. For example, the scattering properties varies with the particle size so that particles of different size scatter the light into different directions.

The at least bi-modal particle size distribution can be relative to pigment microparticles formed by the same pigment material. In addition to that or alternatively, the at least bi-model particle size distribution can be provided by pigment microparticles of different pigment material.

The size of pigment microparticles which can be described to have a 2-dimensional shape, and which are referred to as 2-dimensional microparticles can be determined by SEM. The size of 2-dimensional microparticles can also be determined by laser diffraction measurements. The particle size determined by laser diffraction is a mean size of the different dimensions of the 2-dimensional particles. The apparent D50[vol] particle diameter of 2-dimensional microparticles, as measured by SEM, can be from 0.5 micron to 50 microns, more preferably from 0.8 micron to 20 microns, more preferably from 1 micron to 15 microns, more preferably from 1.5 micron to 10 microns.

According to an embodiment, pigment particles are referred to as being microspheres can be used light-scattering and/or light absorbing purposes. Those particles, due to their pigment material, impart the hair with a specific color.

According to an embodiment, pigment particles are referred to as being 2-dimensional microparticles can be mainly used for light-reflecting and/or light absorbing purposes. Those particles, due to their pigment material, mainly reflect the light without significantly alter the color of the light.

The pigment microparticles can be light absorbing, but which for wavelengths of visible light provide negligible to low or no scattering. While not wishing to bound by any specific theory, it is believed that such pigments can provide more chromatic colors. Such pigment microparticles can have a D50[vol] value between about 0.001 micron and about 0.15 micron, between about 0.005 micron and about 0.1 micron or between about 0.010 micron and about 0.075 micron.

The pigment microparticles can be predominantly light scattering for wavelengths of visible light and provide low light absorption. While not wishing to bound by any specific theory, it is believed that such pigments can provide the visual effect of lightening the hair. Such pigment microparticles, which can be microspheres, can have a D50[vol] value between about 0.05 micron to about about 1 micron, between 0.08 micron to about 0.9 micron, between about 0.05 micron and about 0.75 micron, between about 0.1 micron and about 0.5 micron or about 0.15 micron and about 0.4 micron. Such materials can have a refractive index above 1.5, above 1.7 or above 2.0.

Pigments made from metal and metal like materials which can conduct electricity, and which can absorb light and re-emit the light out of the metal to give the appearance of strong reflectance. While not wishing to be bound by any specific theory, it is believed that the absorbed light will induce alternating electric currents on the metal surface, and that this currents immediately re-emit light out of the metal. Such pigment microparticles can be platelets, e.g., having a thickness that is substantially smaller than the planar dimension. For example about five, about 10 or even about 400 times smaller in thickness than in the planer. Such platelets can have a planar dimension less than about 30 nm, but with a thickness less than about 10 micron wide. This includes a ratio of 10000 to 30, or 333. Platelets larger in size, such as 50 microns are even available in this thickness of 10 microns, and so the ratios can even go up to 2000.

The pigment microparticles can be a composite formed by two different types of pigment microparticles. Examples include a composite of a 2-dimensional microparticle and at least one micro spherical particle (microsphere), a composite of different micro spherical particles, and a composite of different 2-dimensional particles. Composite particles formed by 2-dimensional microparticles to which micro spherical particles adhere provide an attractive alternative to a pure mixture of 2-dimensional microparticles and micro spherical particles. For example, a metallic 2-dimensional microparticle can carry one or more micro spherical particle such as one or more organic micro spherical particle. The micro spherical particles attached or bonded to the 2-dimensional microparticle can be formed of the same pigment material or can be formed of different pigment material. Composite microparticles formed of 2-dimensional microparticles and micro spherical particles can provide multiple functionality in one particle such as (metallic) reflectance and dielectric scattering, reflectance and absorption.

Pigment microparticles may be materials which are composite comprising a core of pigments made from metal and metal like materials which can conduct electricity, and which can absorb light and re-emit the light out of the metal to give the appearance of strong reflectance. While not wishing to be bound by any specific theory, it is believed that the absorbed light will induce alternating electric currents on the metal surface, and that this currents immediately re-emit light out of the metal. Upon this pigment light absorbing microparticles is immobilized. Such pigment microparticles can be platelets, e.g., having a thickness that is substantially smaller than the planar dimension. For example, five, ten or even 20 times smaller in thickness than in the planer. Such platelets can have a planer dimension less than 15 microns, but with a thickness less than 1 microns, more preferably with a planer dimension less than 12 microns but with a thickness less than 750 nm, even more preferably with a plan dimension less than 10 microns and a thickness less than 0.5 micron. The light absorbing microparticles can have D50 [vol] value between 0.001 micron and 0.15 micron, more preferably between 0.002 micron and 0.1 micron and even more preferable between 0.005 micron and 0.075 micron.

The light absorbing microparticles may also include dyes, pigments, or materials with color centers in the crystal structure, or photonic structures resulting in destructive or constructive interference, diffraction or other structures and materials mentioned in the book “The Physics and Chemistry of Color: the Fifteen Causes of Color”, 2^(nd) Edition by K.I. Nassau (ISBN 978-0-471-39106-7).

The pigment microparticles can be both light scattering and absorbing for wavelengths of visible light. While not wishing to bound by any specific theory, it is believed that such pigments can provide both some visual effect of lightening the hair. Such pigment microparticles can have a D50[num] value between about 50 nm and about 750 nm, between about 100 nm and about 500 nm or between about 150 nm and about 400 nm. Such materials have a refractive index above about 1.5, above about 1.7 or above about 2.0.

According to an embodiment, different pigment microparticles are combined to provide reflective, transmitting and refractive properties of the hair colored with the color composition described herein. A microparticle combination can be a material composite using at least two different pigment materials to form the pigment microparticles. In addition to, or alternating to, the microparticle combination, a mixture of separate pigment microparticles of different type can be used to bring about the desired reflective, transmitting and refractive properties.

The composite pigments, combination of pigments, and mixtures of pigment microparticles eliminate, or at least significantly reduce, hair penetration and scattering by light and thus eliminate the perception of pigment of natural hair color change.

The at least one pigment in accordance with the present disclosure can also be in the form of at least one composite pigment as described in European Patent Publication No. EP 1 184 426 A2. These composite pigments can be, for example, compounds of particles comprising a mineral core, at least one binder for ensuring the binding of the organic pigments to the core, and at least one organic pigment at least partially covering the core.

The at least one pigment in accordance with the present disclosure can be in the form of small undissolved microparticles, which do not diffuse into the hair color, but deposit on the outer wall of the keratin fiber. Suitable color pigments can be of organic and/or inorganic origin. But the pigments can also be inorganic color pigments, given the excellent light, weather and/or temperature resistance thereof.

Inorganic pigments, whether natural or synthetic in origin, include those produced from chalk, red ocher, umbra, green earth, burnt sienna or graphite, for example. Furthermore, it is possible to use black pigments, such as iron oxide black, color pigments such as ultramarine or iron oxide red, and fluorescent or phosphorescent pigments as inorganic color pigments.

Colored metal oxides, metal hydroxides and metal oxide hydrates, mixed phase pigments, sulfurous silicates, silicates, metal sulfides, complex metal cyanides, metal sulfates, metal chromates and/or metal molybdates are particularly suitable. In particular, preferred color pigments are black iron oxide (CI 77499), yellow iron oxide (CI 77492), red and brown iron oxide (CI 77491), manganese violet (CI 77742), ultramarine (sodium aluminum sulfosilicates, CI 77007, Pigment Blue 29), chromium oxide hydrate (CI 77289), iron blue (ferric ferrocyanide, CI 77510) and/or carmine (cochineal).

The at least one pigment can also be colored pearlescent pigments. These are usually mica-based and can be coated with one or more metal oxides from the group consisting of titanium dioxide (CI 77891), black iron oxide (CI 77499), yellow iron oxide (CI 77492), red and brown iron oxide (CI 77491, CI 77499), manganese violet (CI 77742), ultramarine (sodium aluminum sulfosilicates, CI 77007, Pigment Blue 29), chromium oxide hydrate (CI 77289), chromium oxide (CI 77288) and/or iron blue (ferric ferrocyanide, CI 77510).

Mica forms part of the phyllosilicates, including muscovite, phlogopite, paragonite, biotite, lepidolite, and margarite. To produce the pearlescent pigments in combination with metal oxides, the mica, primarily muscovite or phlogopite, is coated with a metal oxide.

As an alternative to natural mica, it is also optionally possible to use synthetic mica coated with one or more metal oxides as the pearlescent pigment. Such suitable pearlescent pigments based on natural micas are described in, e.g., WO 2005/065632. The at least one pigment can also be pearlescent pigments based on natural or synthetic mica and are coated with one or more of the aforementioned metal oxides. The color of the respective pigments can be varied by varying the layer thickness of the metal oxide or metal oxides.

The at least one pigment can also be at least one inorganic color pigment selected from the group consisting of colored metal oxides, metal hydroxides, metal oxide hydrates, silicates, metal sulfides, complex metal cyanides, metal sulfates, bronze pigments and/or colored pigments based on mica, which are coated with at least one metal oxide and/or a metal oxychloride.

Depending on the degree of the change in color that is desired on the keratin fiber, the at least one pigment can also be can be used in varying amounts. The more color pigment that is used, the higher is the extent of the change in color in general. Starting at a certain usage amount, however, the adherence of the pigments to the keratin fiber approaches a limiting value, beyond which it is no longer possible to increase the extent of the change in color by further increasing the pigment amount used. While not wishing to be bound by any specific theory, it is believed that when a certain thickness is achieved, an insignificant amount of the incident lights passes through the pigment layer to make a difference to the observed color due to the hair itself. The rest of the light is either scattered back towards the surface, or absorbed.

The at least one pigment can be partially (Scheme 1, (b), where the dark oval represents a pigment, even though the pigment can be white or colorless) or completely enveloped in a matrix (e.g., a polymer matrix or an inorganic matrix; (Scheme 1, (a)). Or the pigment can be adhered to the surface of a matrix that can be colored or colorless (Scheme 1 (c)).

The matrix can be, e.g., CaCO₃, MnCO₃. Or the matrix can be a melamine formaldehyde matrix.

In another example, the at least one pigment can be encapsulated in silica, as described in Published U.S. Appl. No. 2007/0134180. Other examples of encapsulated pigments include encapsulated Carmine, Iron Oxides, Titanium dioxide, and Chrome Oxide/Hydroxide, the colorants D&C Red 21 Aluminum Lake, D&C Red 7 Calcium Lake, D&C Green 6 Liposoluble, and Aluminium Blue #1 (Indigo Carmine Lake). The encapsulated pigment can be titanium dioxide (used to lighten other pigments and to lend opacity to formulations) in any one of its mineral forms anatase, brookite or rutile, or mixtures thereof. Or the pigment can be at least one iron oxide in any of the 3 basic colors—red, black and yellow iron oxides, or mixtures thereof. From these 3 oxides and the addition of titanium dioxide, any shade of brown (skin tones) can be achieved.

The organic pigment can also be a lake. As used herein, the term “lake” means at least one dye adsorbed onto insoluble particles, the assembly thus obtained remaining insoluble during use. The inorganic substrates onto which the dyes are adsorbed can be, for example, alumina, silica, calcium sodium borosilicate, calcium aluminum borosilicate, calcium carbonate, manganese carbonate, aluminum, nitro-dyes, triarylmethin dyes, Azo-dyes, Anthrazen, Acid dyes, polymethine dyes, triarylmethin dyes, aza annulene dyes and polymethine dyes.

Among the dyes, non-limiting mention can be made of cochineal carmine. Non-limiting mention can also be made of the dyes known under the following names: D&C Red 21 (CI 45 380), D&C Orange 5 (CI 45 370), D&C Red 27 (CI 45 410), D&C Orange 10 (CI 45 425), D&C Red 3 (CI 45 430), D&C Red 4 (CI 15 510), D&C Red 33 (CI 17 200), D&C Yellow 5 (CI 19 140), D&C Yellow 6 (CI 15 985), D&C Green (CI 61 570), D&C Yellow 1 O (CI 77 002), D&C Green 3 (CI 42 053), and D&C Blue 1 (CI 42 090). A non-limiting example of a lake that can be mentioned is the product known under the following name: D&C Red 7 (CI 15 850:1).

The at least one pigment can also be a pigment with special effects. As used herein, the term “pigments with special effects” means pigments that generally create a non-uniform colored appearance (characterized by a certain shade, a certain vivacity, and a certain lightness) that changes as a function of the conditions of observation (light, temperature, observation angles, etc.). They thus contrast with white or colored pigments that afford a standard uniform opaque, semi-transparent, or transparent shade.

Several types of pigments with special effects exist, including those with a low refractive index, such as fluorescent, photochromic, or thermochromic pigments, and those with a high refractive index, such as nacres or glitter flakes. Examples of pigments with special effects of which non-limiting mention can be made include nacreous pigments such as mica coated with titanium or with bismuth oxychloride, colored nacreous pigments such as titanium mica with iron oxides, titanium mica for example with ferric blue or with chromium oxide, titanium mica with an organic pigment of the abovementioned type, and also nacreous pigments based on bismuth oxychloride. Nacreous pigments of which non-limiting mention can be made include the CELLINI nacres sold by Engelhard (mica-TiO₂-lake), PRESTIGE sold by Eckart (mica-TiO₂), PRESTIGE BRONZE sold by Eckart (mica-Fe₂O₃), and COLORONA sold by Merck (mica-TiO₂—Fe₂O₃).

In addition to nacres on a mica support, multilayer pigments based on synthetic substrates such as alumina, silica, sodium calcium borosilicate, calcium aluminum borosilicate, and aluminum, can be envisaged.

Non-limiting mention can also be made of pigments with an interference effect that are not fixed onto a substrate, for instance liquid crystals (HELICONES HC from Wacker) and holographic interference flakes (GEOMETRIC PIGMENTS or SPECTRA F/X from Spectratek). Pigments with special effects also comprise fluorescent pigments, whether these are substances that are fluorescent in daylight or that produce an ultraviolet fluorescence, phosphorescent pigments, photochromic pigments, thermochromic pigments, and quantum dots, sold, for example, by the company Quantum Dots Corporation.

Quantum dots are luminescent semiconductive nanoparticles capable of emitting, under light excitation, irradiation with a wavelength ranging from 400 nm to 700 nm. These nanoparticles are known from the literature. They can be manufactured, for example, according to the processes described, for example, in U.S. Pat. Nos. 6,225,198 or 5,990,479, in the publications cited therein, and also in the following publications: Dabboussi B. O. et al. “(CdSe)ZnS core-shell quantum dots: synthesis and characterization of a size series of highly luminescent nanocrystallites” Journal of Physical Chemistry B, vol. 101, 1997 pp. 9463-9475 and Peng, Xiaogang et al. “Epitaxial growth of highly luminescent CdSe/CdS core/shell nanocrystals with photostability and electronic accessibility”, Journal of the American Chemical Society, vol. 119, No. 30, pp. 7019-7029.

The variety of pigments that can be used in the present disclosure makes it possible to obtain a wide range of colors, and also optical effects such as metallic effects or interference effects.

The pigments that can be used in the present disclosure can transmit light of various wavelengths, including visible light (e.g., light having a wavelength of above 350 nm). The pigment(s) can also transmit light of certain wavelengths, but also reflect light of certain wavelengths. And the pigment(s) can also be 100% reflective. For examples, reflective pigments provide a high specular reflection of visible light. Reflective pigments include those that are partially or completely coated with a non-matt and non-scattering surface layer of a metal or metal oxide. The substrate can be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, especially aluminosilicates and borosilicates and synthetic mica (e.g., fluorophlogopite), to name a few. The metal or metal oxide can be, without limitation, titanium oxides, iron oxides, tin oxide, chromium oxide, barium sulfate, MgF₂, CeF₃, ZnS, ZnSe, SiO₂, Al₂O₃, MgO, Y₂O₃, SeO₃, SiO, HfO₂, ZrO₂, CeO₂, Nb₂O₅, Ta₂O₅ and MoS₂, and mixtures thereof. Reflective pigments can have a spectral reflectance in the visible spectrum of at least 70%.

Other reflective pigments include those having non-goniochromatic layered structure of two or more polymeric and/or metallic layers of different refractive indices. For example, reflective particles comprising layers of 2,6-polyethylene naphthalate (PEN) and of polymethyl (meth)acrylate are sold by 3M under the name Mirror Glitter™. Other effect pigments are available under the trade name Metasomes Standard/Glitter in various colors (yellow, red, green, blue) from Flora Tech.

Color Gamut for Pigment Blends

CIE L*a*b* (CIELAB) is a color space specified by the International Commission on Illumination. It describes all the colors visible to the human eye and serves as a device-independent model to be used as a reference.

The three coordinates of CIELAB represent the lightness of the color (L*=0 yields black and L*=100 indicates diffuse white; specular white may be higher), its position between red/magenta and green (a*, negative values indicate green while positive values indicate magenta) and its position between yellow and blue (b*, negative values indicate blue and positive values indicate yellow).

Since the L*a*b* model is a three-dimensional model, it can be represented properly only in a three-dimensional space. Two-dimensional depictions include chromaticity diagrams: sections of the color solid with a fixed lightness.

Because the red-green and yellow-blue opponent channels are computed as differences of lightness transformations of (putative) cone responses, CIELAB is a chromatic value color space.

In the present invention, the color gamut is determined by adding each pigment to be tested in the hair coloring composition, and then individually tested at a level such that when applied to hair, the resulting CIELAB lightness or L* value of the colored hair is 60±2. The level of pigment needed will depend on the pigment being tested. Two hair tresses (Kerling, Natural White special quality) have the hair coloring composition applied as described in the present invention. A Minolta spectrophotometer CM-2600d is used to measure the color of the dried hair tresses, five points on both the front and back sides, and the values averaged. The D65 L*a*b values are calculated. When at least three pigments have each been measured such that their resulting color reside within the target L* values of 60±2 the color gamut can be calculated. First the lengths of each side of the resulting triangle of each combination of three pigments in the a*b plane are computed using the following expressions. To calculate the distance between pigments 1 and pigment 2 the following equation is used:

Side Length SL₁₂=((a _(pigment 1) −a _(pigment 2))²+(b _(pigment 1) −b _(pigment 2))²)^(0.5).

This is computed for each pair of pigments. Then for a series of three pigments.

The resulting color gamut is calculated using the expression:

Color Gamut=(S(S−SL₁₂)(S−SL₁₃)(S−SL₂₃))^(0.5)

wherein SL₁₂, SL₁₃, and SL₂₃ are the three lengths of the sides of the triangle within the a*b plane, and S=(SL₁₂+SL₁₃+SL₂₃)/2. Where more than three pigments are used, this calculation can be performed for each combination of the three pigment from the more than three pigments used, and the largest Color Gamut is selected.

The hair coloring composition embodiments of the present invention can also have a color gamut of greater than 250, greater than 500, greater than 750, greater than 800, greater than 900, greater than 1100 or even greater than 1250.

Experiments Performed for Color Gamut

Using the above expression, for each combination of three pigments possible from Color Gamut Tables 1, as illustrated below, the color gamut at a nominal L value of 60 was calculated.

A few examples are exemplified of combinations of pigments and their resulting color gamut. One skilled in the art would be able to perform this for all of the possible permutations of pigments that are assessed according the description above. FIGS. 1 to 4 show plots of color gamut triangles created for a series of three pigment selections.

FIG. 1 shows that a combination of Pigment Green 36, Pigment Yellow 83 and Pigment Red 122 a large triangle is plotted in the a*b* color plane with an area of 1520.

FIG. 2 shows that a combination of Pigment Green 36, Pigment Yellow 83 and Pigment Blue 60 gives a smaller triangle win an area of 925.

FIG. 3 shows that a combination of Pigment Black 7, Pigment Yellow 83 and Pigment Red 122 gives a smaller triangle win an area of 655.

FIG. 4 shows that a combination of Pigment Black 7, Pigment Blue 60 and Pigment Red 122 gives a smaller triangle win an area of 92.

A second series of example are made for how to assess more than three pigments and their resulting color gamut. When plotted a series of triangles can be plotted as shown and for each the areas is assessed. For such a system the color gamut is defined as the largest of the triangles formed.

FIG. 5 shows that a combination of Pigment Green 36, Pigment Yellow 83, Pigment Blue 60 and Pigment Red 122 a series of triangles are plotted with areas of 803, 925, 209 and 1520. The color gamut of this pigment system is 1520. [Alterative calculation of total area would yield, 1728]

FIG. 6 shows that a combination of Pigment Black 7, Pigment Yellow 83, Pigment Blue 60 and Pigment Red 122 a series of triangles are plotted with areas of 803, 57, 92 and 655. The color gamut of the pigment system is 803 [alternative approach would be the same]

E. The pH

The bicomponent composition embodiments in accordance with the present disclosure can have a pH ranging from about 3 to about 12, preferably about 4 to about 10 and in many embodiments 6.8 or higher. For example, the pH can be 8 or higher, 9 or higher or at most 12. In some examples, the bicomponent composition embodiments in accordance with the present invention can have a pH of from about 7 to about 10, about 5 to about 11 or about 6 to about 8.

The bicomponent composition in accordance with the present disclosure can comprise a pH modifier and/or buffering agent. The amount is sufficiently effective to adjust the pH of the composition/formulation. Suitable pH modifiers and/or buffering agents for use herein include, but are not limited to: ammonia, alkanolamines such as monoethanolamine, diethanolamine, triethanolamine, monopropanolamine, dipropanolamine, tripropanolamine, tripropanolamine, 2-amino-2-methyl-1-propanol, and 2-amino-2-hydroxymethyl-1,3,-propandiol and guanidium salts, alkali metal and ammonium hydroxides and carbonates, such as sodium hydroxide, sodium silicate, sodium meta silicate and ammonium carbonate, and acids such as inorganic and inorganic acids, e.g., phosphoric acid, acetic acid, ascorbic acid, citric acid or tartaric acid, hydrochloric acid, and mixtures thereof.

F. Dispersants

It will be apparent to one skilled in the art that careful and selective choice of dispersant can help to maximize performance in terms of maximizing the amount of color produced from an immobilized film, maximizing the remanence or washfastness, and enabling removal of the color.

For example, in the case where the binder polymer is anionic in nature, dispersants which are anionic or nonionic are preferably chosen, rather than cationic, as this avoids undesired precipitation in the formula prior to it forming a colored film on the keratin—i.e. utilizing the principle of avoiding opposing charges.

Likewise, the principle of choosing chemically similar dispersant and binder (for example, a silicone binder paired with a silicone dispersant, can be followed to ensure maximum compatibility.

As well as compatibility as noted above, the other critical criterion in selecting dispersant(s) is their ability to enable pigment to be dispersed down to the primary particle size, preferably with the minimum amount of input mechanical energy. It will be recognized by someone skilled in the art that the concentration of dispersing agent is also a critical factor. In general it is usually required that there is a minium amount for dispersing activity and that below this, the system is either not fully dispersed or, worse, that the dispersant acts as a flocculant.

These two considerations together are used to define preferred materials and their respective concentrations.

It may also be the case, depending on the type of binder polymer used, that the binder itself is also a dispersant (see below for discussion of classes of dispersant). In such cases it is possible that no further dispersing additive may be needed.

Overview of Dispersant Kinds, Properties and Chemistry

Dispersants are amphiphilic or amphiphathic meaning that they are chemical compounds possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving) properties. Dispersants are surface-active polymers that allow the homogeneous distribution and stabilization of solids, e.g. pigments in a liquid medium (like a binder), by lowering the interfacial tension between the two components. As a result, agglomerates are broken up into primary particles and protected by a protecting dispersant envelope of a re-agglomeration.

The dispersants can be subdivided on the basis of the stabilization mechanism in

-   -   a. Anionic dispersing additives         -   i. Polyacrylates         -   ii. Polyphosphates     -   b. Neutral dispersing additives     -   c. Cationic dispersing additives

2. Dispersants for steric stabilization

Electrostatic Stabilization

The pigment surface is occupied by an additive carrying an ionic charge. All pigment particles are charged the same. The mutual repulsion by the charge is greater than the attractions of the pigment particles. The electrostatic stabilization has its relevance mostly in water-based paint systems.

-   -   Polyanionic dispersing additives: polycarboxylates (mostly salts         of polyacrylic acids), polyphosphates divided into linear         polyphosphates and cyclic metaphosphates, polyacrylates     -   salts of polyacrylic acid, as cations, sodium and ammonium are         preferred, these polyacrylates are water-soluble, technical         products have molecular weights in the range of 2000 to 20,000         g/mol, optimum is about 8000 g/mol     -   Sodium and ammonium salts of the homo- or copolymers of acrylic         acid, methacrylic acid or maleic acid

Steric Stabilization

The attractive forces between the pigment particles are effective only over relatively small distances of the particles from each other. The approach of two particles to each other can be prevented by molecules that are firmly anchored to the pigment surface and carry groups that extend from the surface and may reduce the potential for the pigments to contact one another. By sufficiently long chain lengths, agglomeration can be prevented.

-   -   Water-soluble polymers     -   Block or graft copolymers, so-called AB block copolymers     -   Example: AB block polymer of 2-vinylpyridine and methacrylic         acid ester     -   Example: AB block copolymer of polyester (based caprolactam) and         triethylenetetramine     -   Typical functional groups for the A segment are carboxyl, amine,         sulfate and phosphate for inogenous bonds or polyether and         polyamide for hydrogen bonds. B represents the solvated side         chain, molecular weights 1000 to 15000 g/mol, e.g. modified         polyacrylates or polyhydroxystearates     -   Hydrophilic moieties (e.g., polyethers) and pigment affinic         groups (e.g. Groups) containing oligomers or polymers.

The following types are distinguished according to the number of monomer types used in the production:

-   -   Homopolymers: only one kind of monomer     -   Copolymers: two monomers     -   Terpolymers: three monomers

Classification according to distribution of the monomers in the polymer:

-   -   Statistical polymers: A and B segments are distributed         arbitrarily     -   Block polymers: the monomers are grouped into blocks     -   Graft polymers: these consist of a linear homopolymer backbone         on which side chains of other monomer blocks are grafted

Some examples of dispersants for solvent-based systems are:

-   -   oligomeric titanates and silanes for inorganic pigments with OH         or carboxy groups.     -   Oligomeric polymeric carboxylic acids for inorganic pigments         (cationic).     -   Polyamines for inorganic pigments, e.g., cationic polymers.     -   Salts of long-chain polyamines and polycarboxylic acids for         inorganic and organic pigments (electroneutral).     -   Amine/amide-functional polyesters/polyacrylates for the         stabilization of organic pigments.

Some examples of dispersants for aqueous systems are:

-   -   Inorganic dispersants such as fine-grained CaCO3, Ca3 (PO4) 2,         polyphosphates, polyphosphoric acids.     -   Nonionic surfactants such as ethoxlyated fatty alcohol (e.g.         Neodol 25-9), ethoxylated oils (e.g. ethxylated castor oil under         the tradename Cremophore RH410)     -   Block and graft copolymers of the type having distinct         hydrophilic and hydrophobic blocks (e.g. ethylene         oxide-propylene oxide polymers under the tradename Poloxamer)     -   Anionic surfactants consisting of the unethoxylated or         ethoxylated salts of acids (e.g. sodium ceteth-10-phosphate         under the tradename Crodafos).

Examples and classes of nonionic surfactants that can function as dispersants include oligomers (e.g., example, oligomers have up to 20 monomeric units, polymers have at least 20 monomeric units), polymers, and/or a mixture of several thereof, bearing at least one functional group with strong affinity for the surface of the pigment microparticles. For example, they can physically or chemically attach to the surface of the pigment microparticles. These dispersants also contain at least one functional group that is compatible with or soluble in the continuous medium. For example, 12-hydroxystearic acid esters and C₈ to C₂₀ fatty acid esters of polyols such as glycerol or diglycerol are used, such as poly(12-hydroxystearic acid) stearate with a molecular weight of about 750 g/mol, such as the product sold under the name SOLSPERSE 21,000 by the company Avecia, polyglyceryl-2 dipolyhydroxystearate (CTFA name) sold under the reference DEHYMYLS PGPH by the company Henkel, or polyhydroxystearic acid such as the product sold under the reference ARLACEL P100 by the company Uniqema, and mixtures thereof. Similar dispersants will function to disperse the polar functional silicone polymers that are not readily dispersible and/or are not at least partially soluble in aqueous media.

The foregoing dispersant category involving cationic polymers includes polymers such as quaternary ammonium polymers. Examples of quaternary ammonium derivatives of polycondensed fatty acids include, such as for instance, SOLSPERSE 17,000 sold by the company Avecia, and polydimethylsiloxane/oxypropylene mixtures such as those sold by the company Dow Corning under the references DC2-5185 and DC2-5225 C.

The dispersant can be a polyolefin polymer. These dispersants include but are not limited to an olefinic polymer having a molecular weight of about 100 g/mol to about 5,000,000 g/mol, such as about 1,000 g/mol to about 1,000,000 g/mol. Examples of polymers, include, but are not limited to poly(ethylene), poly(propylene), poly(butylene), poly(isobutylene), poly(isoprene), poly(acetal), poly(ethylene glycol), poly(propylene glycol), poly(butylene glycol), poly(methylmethacrylate), poly(dimethylsiloxane), poly(vinylalcohol), poly(styrene), poly(maleic anhydride), poly(ethylmethacrylate), poly(isobutylmethacrylate), poly(methacrylate), poly(butylmethacrylate), poly(n-butylmethacrylate), poly(vinyl butyrate), poly(vinyl chloride), polysiloxane, and mixtures thereof. The polymers can be random, block, or alternating copolymers. In some embodiments, the polymer is a co-polymer that is made from two or more different monomers, such as the monomers that make the polymers described above. Examples of co-polymers include, but are not limited to polyethers, polyesters, polyamides, acrylics, and polystyrenes. The co-polymer can be alternating monomers, random, or block. Examples include a polyether of alternating or block PEO, PPO groups. Examples of acidic groups include, but are not limited to, carboxylic acids, sulfinic acids, sulfonic acids, phosphonic acids, phosphate esters, maleic anhydrides, and succinic anhydride. In some embodiments, the dispersive additive comprises a group selected from phosphonate, phosphate, phosphite, phosphine, and phosphate ester, such as a phosphate, phosphite, and phosphonic acid. In some embodiments, the acidic group has been converted into a salt.

Following the foregoing principles and guidelines, the pigment microparticles can be dispersed in the composition with the addition of at least one of a dispersant and a wetting agent. While not wishing to be bound by any specific theory, it is believed that only when the pigments are de-aggregated into their primary particles do they deliver the optimum optical performance. For examples, pigments with a primary particle size of 0.02 micron which provide brilliant bright colors, when present as aggregates of around 0.3 micron provide duller colors.

The dispersant serves to protect the pigment microparticles against agglomeration or flocculation either in the dry state or in the solvent. Dispersants also serve as wetting agents. In this capacity, dispersants as wetting agents can be low or higher molecular weight monomeric surfactants (for example, anionic, cationic or amphoteric surfactants). Dispersants as wetting agents can be higher molecular weight surface-active or pigment particle affinic polymers (for example, polyelectrolyte dispersants such as maleic acid copolymers, and polyurethanes or polyacrylates containing carboxylic acid, amine or isocyanate pigment affinic anchor groups or polyethylene imines) or other type of polyelectrolytes.

Representative wetting agents include those available from a variety of suppliers including Air Products and Chemicals (e.g., CARBOWET™ GA-210 surfactant which has a viscosity of 80 cps, CARBOWET GA-221 surfactant which has a viscosity of 100 cps, DYNOL™ 607 superwetter which has a viscosity of 205 cps and DYNOL 800 superwetter which has a viscosity of 230 cps); Dow Chemical Co. (e.g., CAPSTONE™ fluorosurfactants FS 31, FS 34, FS 35, FS 61 and FS 64); and Stepan Company (e.g., STEPWET™ DOS-70 surfactant which contains 70% active ingredients and has a viscosity of 200 cps, and STEPWET DOS-70EA surfactant which contains 70% active ingredients and has a viscosity of 220 cps).

G. Incorporation of Pigment in Dispersant

The pigments described herein can be chosen and/or modified to be similar enough such that a single dispersant can be used. In other instances, where the pigments are different, but compatible, two or more different dispersants can be used. Because of the extreme small size of the pigment microparticles and their affinity, combination of the pigment microparticles and dispersant to form a substantially homogeneous dispersion that can subsequently be modified and/or diluted as desired is to be accomplished before combination with any or all of the first and second components of the bicomponent composition.

The pigment microparticles can be dispersed and stabilized in the medium by one or more dispersants the properties and kinds of which are described above. The dispersant can either be added to the medium, or to a precursor medium or can form a coating on the microparticles to facilitate dispersion. It is also possible to provide the microparticles with a coating of a dispersant material and additionally provide a further dispersant to the medium, or to a precursor medium, which is used to form the final medium.

The dispersant, either added to the medium or provided as coating, facilitates wetting of the microparticles, dispersing of the microparticles in the medium, and stabilizing of the microparticles in the medium.

The wetting includes replacing of materials, such as air, adsorbed on the surface of the pigment microparticles and inside of agglomerates of the microparticles by the medium. Typically, a complete wetting of the individual microparticles is desired to singularize the particles and to break off agglomerates formed by microparticles adhering to each other.

After wetting, the microparticles can be subjected to de-aggregate and de-agglomerate step, generally referred to as dispersing step. The dispersing step typically includes the impact of mechanical forces such as shear to singularize the microparticles. In addition to shearing to singularize, the microparticles can be broken into even smaller microparticles using, for example, roller mills, high speed mixers, and bead mills. Usual practice involves substantially homogeneous dispersion of the pigments in dispersant through the use of high shear mixing; for example through use to the appropriate ball mill, ultra high pressure homogenizer or other system known by those skilled in the art of pigment dispersion.

During wetting and dispersing, the exposed total surface area of the microparticles increases which is wetted by the dispersant. The amount of the dispersant may be gradually increased during dispersing to account for the increased surface area.

The dispersant also functions as de-flocculation agent keeping the dispersed microparticles in a dispersed state and prevent that they flocculate to form loose aggregates. This stabilization is also needed for long term storage purposes. Different type of stabilization such as electrostatic stabilization and steric stabilization are possible, and the type of dispersant is selected in view of the medium and the material of the microparticles.

The dispersant may be added to a dry powder of the pigment particles when the particles are milled to a desired size. During milling, or any other suitable technique to singularize the pigment particles or to break them into smaller part, the dispersant comes in contact with and adheres to the surface of the microparticles. Freshly generated microparticle surface during milling will be coated by the dispersant so that, after milling, the microparticles with a coating formed by the dispersant are provided.

The coating with the dispersant can also be carried out in a liquid carrier medium to which the dispersant is added. The microparticles can also be milled in the liquid carrier.

H. Optional Components

Optional components of the composition include suspending agents, leveling agents and viscosity control agents. The suspending agents help maintain the pigment particles in dispersed condition and minimize or negate their agglomeration. Suspending agents include fatty acid esters of polyols such as polyethylene glycol and polypropylene glycol. These are similar to plasticizers and function in similar fashion to allow pigment particles to “slip” by each other without retarding or binding interaction. They act as grease in this fashion. Additionally, suspending agents in part participate in promoting the stable dispersion of the pigment particles and avoid settling. The carboxylic acid polymer also participates through its solubilization or interaction with the pigment particles and with the medium. The suspending agents provide another factor for maintaining the stable dispersion. They not only provide the “grease” to facilitate Brownian movement but also in part stabilize through interaction as emulsifiers of the pigment particles in the medium.

The bicomponent composition embodiments in accordance with the present invention can also optionally contain at least one adjuvant, chosen, for example, from reducing agents, fatty substances, softeners, antifoams, moisturizers, UV-screening agents, mineral colloids, peptizers, solubilizers, fragrances, anionic, cationic, nonionic, or amphoteric surfactants, proteins, vitamins, propellants, oxyethylenated or non-oxyethylenated waxes, paraffins, C₁₀-C₃₀ fatty acids such as stearic acid or lauric acid, and C₁₀-C₃₀ fatty amides such as lauric diethanolamide.

Included at least are the carboxylic acid polymer and the pigment microparticles of the bicomponent composition. The medium, in contrast is a liquid and functions as a solvent and/or a liquid in which solid particles are dispersed. The optional components as well as the plasticizer, dispersing agent, surface treatment agent, cross linking agent and other materials added to the medium, if any, are included in the solids content as long as they remain with the carboxylic acid polymer and pigment microparticles following application and setting of the bicomponent composition as a coating on strands of human hair. This includes substances that ordinarily would be regarded as liquids because they would remain in the coating on strands of hair. The solids content of the bicomponent composition may range from about 1 wt % to about 40 wt % relative to the total weight of the composition. A preferred solids content ranges from about 2 wt % to about 30 wt % and another preferred solids content ranges from about 4 wt % to about 20 wt % relative to the total weight of the composition. An especially preferred solids content range is about 4 wt % to about 10 wt % with contents of about 5 wt %, about 6 wt %, about 7 wt %, about 8 wt %, about 9 wt % and about 10 wt % being more especially preferred.

Testing the Flexibility of a Coating of the Bicomponent Composition

With the film prepared above, it can also be tested for optical density to check that the polymer film does not itself alter the hair appearance of the hair too significantly.

Further the polymer preferably can have a glass transition point (Tg) as described above so that it is possible to prevent the colored coating from being damaged or cracked and to secure washing and friction fastness.

The composition coating can have a surface energy between about 20 and about 50 mN m⁻¹ (SI unit?) mJ m⁻². The composition coating preferably has high transmission, to ensure that it does not interfere with the optics of the hair color. The polymer preferably has a refractive index between 1.4 and 1.6.

Application of First and Second Components of the Bicomponent Composition to Treated Material or Textiles

The first and second components of the bicomponent composition may be maintained in separate storage compartments or in separate kit form. A convenient storage means can be utilized such as plastic squeeze tubes, plastic bottles, glass containers, sachets, multi-compartment containers, tooles, spottles syringes and plunger operated dispensing devices. Alternatively, metered or calibrated dispensing containers for providing measured amounts of the components as directed by printed instructions can be provided.

Use of the foregoing delivery means enables preparation of an embodiment for practice of the method of the present invention. This embodiment comprises sequential application of the first and second components to treated material or textiles. Pigment microparticles may be incorporated in either or both of the first and second components.

Pretreatment with Second Component

An embodiment of the method according to the present invention may comprise application of the second component to the treated material as a pretreatment before application of the first component as described above. According to this embodiment of the method, pretreatment with the may be carried out prior to application of the first component. Pretreatment may be carried out immediately prior to application of the first component, or at least 1 hour prior to application of the first component, or at least 24 hours prior to application of the first component, or at least 10 days prior to application of the first second component, or at least one month prior to application of the first component. Preferably, pretreatment may be carried out immediately prior to or within a few minutes up to an hour before application of the first component. Typically, the is at least partially dried with optional heating to at least substantially remove or otherwise eliminate the medium of the. For example excess medium may be removed by contacting with an absorbent fabric or surface or the hair may by heated with a hair drier. Preferably, removal of medium is accomplished before application of the first component.

Core and Shell Alternative

According to an embodiment in which pigment microparticles are incorporated into the, at least some of categories of the base compound can be employed to provide a “core-shell structure” (core-shell morphology) for the pigment microparticles. In the case that the base compound and pigment(s) have a “core-shell structure”, the “core” corresponds to the “naked” pigment which features the same properties as defined hereinbefore with reference to the “pigment(s)”. The “shell” corresponds to a coating layer of base compound surrounding the “core”. The pigments having a core-shell structure may have a D₅₀(Vol)particle diameter of from 20 nm to 1 micron, typically 60 nm to 900 nm, more typically 100 nm to 600 nm. As such, embodiments of the present invention also relate to a bicomponent composition comprising a core-shell pigment microparticle arrangement, wherein the core comprises an inorganic and/or organic pigment microparticle material, and the shell comprises at least one base compound, the at least one core-shell construct having a D₅₀(Vol) particle diameter of 20 nm to 1 μm. The shell surrounding the core may comprise one or more polymeric shell layers. Typically, the shell may comprise a base compound wherein the base compound is a polymeric shell layer.

A further embodiment involving the core and shell alternative may be accomplished by pretreatment of a prepared dispersion of pigment microparticles with a portion of base compound in appropriate medium to provide a dispersion of pigment microparticles as the core and shell construct ready to be combined with any of the first component.

Application of First Component Following Pretreatment

As described above, first component may be applied to the treated material in combination with the foregoing pretreatment. Application of the first component to treated material may be accomplished by application of the first component to the material. The practice of this step with the pre-treatment embodiment initially introduces the first component on top of the pretreatment layer of base compound on the treated material. Because the first component is in a medium, penetration, combination and/or mixing of the first component into the pretreatment layer is believed to be accomplished. The penetration is believed to enable interaction among the organic polymer, the pretreatment base compound and the treated material.

Application of the first component to pretreated treated material is preferably carried out after pretreatment. This sequence may be carried out immediately after pretreatment, or at least 1 hour after pretreatment, or at least 24 hours after pretreatment, or at least 10 days after pretreatment, or at least one month after pretreatment.

The application of the first component may be applied to at least a portion of the treated material or may be applied all over the treated material. The portions of first component may be applied in a single application over all the treated material or may be applied step-by-step to the treated material. The first component may be applied step-by-step, for example, in case the treated material is damaged. Applying the first component in a step-by-step manner as described above, may help to ensure that the treated portions of the treated material are saturated with the first component and may therefore provide a better coverage of the treated material.

The bicomponent composition can be applied to treated material using the coloring procedure described herein afterwards.

Manipulative Techniques for Application

After the pretreatment of the has been accomplished, and the pretreated treated material optionally rinsed, the pretreated treated material can be dried. The treated material can be dried using an elevated temperature. The temperature of the treated material can be increased to elevated temperatures above room temperature such as 40° C. or higher, for example using a hair drier. While the treated material is being dried, some form of interdigitated implement can be used to help separate portions of the treated material, and especially separate hair strands from one another. Examples of interdigitated devices include a comb or a brush. The treated material can be dried with a hair drier while simultaneously being combed or brushed until it is dry to the touch. Alternatively, other means can be employed to dry and separate the treated material such as hair simultaneously. For example, using a combination of air movement and vibrations will accomplish distribution of the bicomponent composition throughout the strands of hair.

Operational Method for Coating Hair

The performance of operational method aspects of the present invention can be applied to keratin fibers to form a coating of the bicomponent composition. This aspect of the invention concerns a method for coloring treated material and comprises applying embodiments of one or more bicomponent compositions for a time sufficient to deposit an effective colored coating on the treated material such as each keratin fiber or hair strand. A somewhat to substantially overall distribution of the coating on the length and circumference of each fiber is produced.

To accomplish this aspect, embodiments of the first component of bicomponent composition are applied to the treated material according to the sequences described above by brushing, painting, spraying, atomizing, squeezing, printing, rubbing massaging or in some manner coating the treated material such as hair strands with the embodiments. Following application of a compositional embodiment to the treated material such as hair strands, the composition is coordinated together preferably by warming with blown warm air from a hair dryer or similarly treated to remove the medium, initiate linking of the organic polymer, the pretreatment base compound, the treated material and if present, remove the volatile base. The setting leaves a substantial to essentially complete overall linked coating of the organic polymer, pretreatment base compound and base compound containing dispersed pigment microparticles and optional additional components.

The combination of the substantive constituents of first and second components during application provides a coating that enables it to resist for a time destruction by washing with dilute mixtures of soap and water or shampoo and water. Color fastness is developed so that washing with dilute aqueous soap solution or dilute aqueous shampoo will not substantially remove the coating, but the coating can be facilely removed by use of a transformation trigger. The properties of the coating include wash-fastness, flexibility, adhesion, abrasion resistance and remanence which are due at least in part to the linked character of the composition constituents including at least the organic polymer, the pretreatment base compound and the base compound and their intermolecular entwining, ionic and electrostatic intermolecular interaction, covalent and/or non-covalent linking, dipole interaction and lipophilic interaction of neutral moieties of these compositional constituents.

Selection of the substantive constituents of the bicomponent composition can be made on the basis of properties such as a solid lattice formation and interaction with the pigment microparticles. Such properties include the flexibility, the hardness, the adhesion, the remanence, the resistance to water or to other chemical compounds, and the abrasion resistance. It is also possible to take advantage of the more versatile properties of block polymers (polymers comprising at least two distinct polymer segments), grafted polymers (polymers containing a polymeric side chain grafted onto the homopolymer or copolymer backbone), or random copolymers (polymers comprising at least two different monomers). In the block copolymers, for example, the amount of hard and soft blocks has a significant impact on the properties of the polymer.

The bicomponent compositions in accordance with the present disclosure can have a viscosity that can be controlled to enable the product to be applied to the hair using either a brush and bowl or a bottle, but with sufficient rheology such that it does not drip and run from the hair onto the face or body.

Alternatively, low viscosity formulations may be applied to the hair via a suitable application device such that it does not drip and run form the hair onto the face and body.

The bicomponent compositions can be utilized in concentrated form or in serial dilutions, to provide for a consistent color results substantially along the entire length of the keratin fibers.

The aspect of coloring mammalian or synthetic keratin fibers with a bicomponent composition as described above includes a method for this coloring. The method comprises:

-   -   (i) applying the above-described bicomponent composition to         keratin fibers an effective coloring amount of the composition         of medium with carboxylic acid polymer, pigment microparticles         and optional additional components;     -   (ii) setting the bicomponent composition by removing or         otherwise eliminating the medium (e.g., by drying the         composition); and.     -   (iii) setting the interaction among the first and second         components third functional groups of the bicomponent         composition by initiating the combination among these groups.

During the setting/drying step, color distribution can be facilitated by concurrently moving and/or stroking the hair with an interdigitating device. Interdigitating devices include a comb or brush. The interdigitating device needs to be pulled substantially along the hair strands from root to tip. It can be pulled through at a rate of 0.1 cm s⁻¹ to 50 cm s⁻¹ or at a rate between 0.5 cm s⁻¹ to 20 cm s⁻¹

The bicomponent composition is applied to the mammalian or synthetic keratin fibers in any suitable way including spraying the bicomponent composition, massaging the keratin fibers by hand, after applying the bicomponent composition to the hand or by combing, brushing or otherwise applying the bicomponent composition throughout the mammalian or synthetic keratin fibers.

Unlike current hair coloring approaches that use dyes, the color with the bicomponent compositions described herein occurs on the surface of the hair strands. Current dye based approaches do provide the head of hair with some color variation, as the strands are not identical, and some of these differences are preserved after coloring. There are also differences root to tip which also helps to provide some variation. Using a pigment based surface coloring system such as that of the present invention, the variation of the underlying hair can be substantially removed, leading to a more homogeneous color result. This color result can be a more homogenous application of color. To obtain a somewhat non-homogeneous application of color that tends toward a more natural look, the user can apply the inventive bicomponent composition by any of several techniques.

The methods by which the bicomponent compositions described herein are applied can be modified, such that the user applies the product in one region of the hair, and then can apply a diluted version in another region of the hair. The dilution formula is specially chosen to be compatible with the colorant formulation and reduces the coloring strength, while maintaining the longevity of the color result. This can effectively be a “blank” formulation, which contains broadly the same materials as the coloring formulation, but with lower or no pigments present. When diluted the ratio of the diluent to colorant can be between about 10:1 and about 1:10, about 8:1 and about 1:2 or about 5:1 and about 1:1.

Alternatively, the amount of bicomponent composition applied can be altered in different regions of the hair, for example half the product is applied in the lengths of the hair, leading to a less colorful result. The difference in amounts applied in one region of the hair versus another can be between about 4:1 and about 1:4 or about 2:1 and about 1:2.

Alternatively, a combination of this approaches may be used to deliver the target color variation.

When the foregoing techniques are not possible to be applied, rather than apply a single hair color, it may be possible to apply two or more hair colors to different regions of the hair. When this is done, the different hair colors preferably provide complimentary colors so as to develop an attractive result. The difference in colors that can be used, based on the end result on hair tresses (as described later—natural white hair non pre-bleached) are as follows. As described within the CIELCh system:

Color 1 (LCh) versus Color 2 (LCh)

Color 1 L-15<Color 2 L<Color 1 L+15 0 or Color 1 C-10<Color 2 C<Color 1 C+10

Color 1 h-45<Color 2 h<Color 1 h+45

Those skilled in the art of color measurements will know how to interpret difference in hue angles, h, when they extend from low positive values to those near to 360 degrees due to the periodic circular nature of the hue angle.

The method for use of the bicomponent composition in accordance with the present invention can occur during any suitable period. The period of application can be from about 0 to 30 minutes, but in any event a period that is sufficiently long to permit the coating of pigment microparticles to coat and adhere or bind to each separate keratin fiber, substantially along the entire length of each keratin fiber. The resultant is keratin fibers having a color and permanence that is at least equivalent to the color resulting from oxidative hair color, except under much milder conditions.

The bicomponent compositions described herein can be prepared by the manufacturer as a full shade, e.g., one that is ready to apply to the hair, and then shipped as a discrete unit to the user. The user may need to re-blend the pigment microparticles with the bicomponent composition prior to application to ensure that the bicomponent composition delivers the optimum performance. Such re-blending can require shaking the bicomponent composition for about 1 to about 120 seconds or from about 3 to about 60 seconds. Reblending may also be performed by stirring the bicomponent composition prior to use. This may occur for about 1 to about 120 seconds or from about 3 to about 60 seconds. Although the bicomponent compositions according to the present invention are designed to provide stable suspensions of the pigment particles, the re-blending to agitate the microparticles and resuspend them in a substantially uniform distribution is desirable.

Alternatively, the bicomponent composition can be made on demand from a series of discrete formulations and mixed ready for use. Each bicomponent composition would need to be designed such that the combinations of two or more bicomponent compositions produce readily mixable bicomponent compositions with sufficient stability to be used. For example, at least four bicomponent compositions can be made available for blending, at least 5 bicomponent compositions and even at least 6 bicomponent compositions. Additional composition may also be used to impart other signals into the product, for example modifying the rheology, changing the perfume, altering the shine or hair feel properties.

Multiple compositions comprising different pigments can be blended together prior to application to the keratin fibers. Such blending can be done in a manner so as to apply a plurality of complementary surface colors to the keratin fibers.

The bicomponent compositions can include multiple layers, involving multiple applications of at least the first and second components. It may be beneficial also to periodically reapply the. The techniques for applying multiple layers follow the techniques described above for application of a single bicomponent composition.

The coating of pigment microparticles comprising at least one pigment in a coating of the substantive constituents of the bicomponent composition can be adhered to the treated material such as hair utilizing a coating having a total thickness at any given point along the hair fiber of less than about 5 μm, preferably less than about 2 μm as measured using a scanning electron microscope (SEM). To make such measurements, a coated hair sample can be embedded in a suitable resin, and then sectioned root to tip using techniques known to those skilled in the art of scanning electron microscopy. The thickness of the layer on the surface can then be assessed along the line of cuticles over a length of at least 100 μm. The thickness of layer is determined by averaging 10 points evenly spaced over the section of interest.

As described above, application of the bicomponent composition to sections of treated material such as sections of hair strands can be varied. In addition to varying the concentration of the pigment microparticles and optional coloring agent, different shades and/or colors of bicomponent composition can be applied to different sections of a strand of hair or a group of strands of hair. For example, the hair roots, mid sections and tips sometimes or often have different shades of color in their natural condition. This variation can be mimicked, altered or covered through use of differing shades or colors of the bicomponent composition. Roots, for example can be covered with a lighter shade and the tips can be covered with a darker shade to produce a two tone variation of the hair. Application to the hair of a first portion of bicomponent composition followed by stripping the composition from the hair mid sections and ends followed by setting the remaining composition on the hair roots will provide a first hair color coating on the roots. The mid-sections and tips can be dipped or brush applied with a second portion of bicomponent composition to complete the two color or two tone treatment. The use of multiple bicomponent compositions to produce multiple coatings on the hair can provide overlapping, sequential or coterminous coatings on the hair according to typical and routine techniques for applying multiple versions of hair color practiced by professional hair salons.

Post Treatment

An optional post treatment composition can be applied after treating the treated material such as hair with the bicomponent compositions described herein. This can be applied either directly after completion of coloring with the bicomponent composition. The post treatment can be either single application or multiple application across time. The post treatment can be used to improve one or more of: feel, resistance to shampoo/conditioner/water washing treatments, and shine of the hair. Nonlimiting examples of materials used to improve the feel are those which impart lubricity to the treated material such as hair strands and/or help the hair strands separate during the drying steps, These materials include, for example silicone conditioners, silicone polyethers, silicone polyglucose, polyisobutene, copolymers of ethylene and propylene oxide, and commonly used cosmetic oils and waxes. Nonlimiting examples of materials used to improve shampoo wash resistance are materials which act as a ‘sacrificial layer’ for example polymeric silicones and their copolymers, silicone resins, cosmetics oils and waxes. Nonlimiting examples of materials used to improve the shine of hair (meaning a decrease of the full width at half maximum parameter of the specular reflection curve as measured by a goniophotometer) are those materials which form a smooth film above the previously applied pigment polymer composite on the hair. In general, any cosmetically known film forming material can be used, but preferred are materials such as polymeric silicones and polycationic materials.

Removal of Color Coating

Hair colorants made from surface films consisting essentially of a binding material plus a pigment, and that are very resistant to everyday hair treatments (such as washing with shampoo, conditioner etc) can be removed via use of specifically designed “removal formulations.” These are specific chemical mixtures, described herein, and are designed to work via one or both of two broad mechanisms.

First, the mixture can be made to be a solvent for the pigment itself. In this case the mechanism of removal involves first dissolution of the pigment from the binding matrix, followed by removal from the hair via rinsing with water or some other carrier. In this case it is believed, whilst not being bound by theory, that the chemical nature of the pigment, even when in dissolved form, is such that there is minimal attraction/solubility in the hair matrix itself, thus allowing removal of the color.

Second, the “removal formulation” can be made such that it dissolves, weakens or chemically breaks down the binder material holding the pigment on the hair. In this case it is believed, whilst not being bound by theory, that the pigments embedded in the binder matrix are released due to weakening or dissolution of the binder itself and, because the coloring material is a pigment, it has minimal attraction for the hair surface and is too big to penetrate the hair, and in consequence this facilitates removal of the color.

The combination of the above mechanisms will also provide the desired result of removal of the color.

Changing the pH can have a dramatic impact on the properties of the coating which is adhered to the surface. A soluble base acting as a trigger agent to neutralize acid groups and enable the conjugate base to be readily soluble in a mixture of water and organic solvent will facilely remove the coating. Such bases include amino alcohols such as dimethylaminoethanol (dimethylethanolamine, DMEA), dimethylaminopropanol, and similar amino alkanol agents such as monoethanolamine, diethanolamine and triethanolamine and ammonia. Other bases such as NaOH and Ca(OH)₂ can also be used. The concentration of the trigger agent in aqueous solution optionally with an alcohol or ketone organic solvent such as methanol, ethanol, methyl ethyl ketone and the like may range from about 0.1% to about 15% by weight, preferably about 0.5% to about 10% by weight, more preferably about 1% to about 7.5% by weight relative to the total weight of the removal solution.

When the multicomponent composition is applied to the hair, the multi-application process physically distributes the components to cover all of the hair. The spraying, massaging, combing and/or hand manipulating the pretreatment and the first and second components produces the full coverage and at the same time leaves thin spots in the otherwise substantially uniform coating. This activity also will aid in the removal process.

Remanence and Treated Material Inspection

Damage caused to the hair by application of the bicomponent composition and removal of the resulting coating can be assessed by FT-IR (Fourier Transform Infrared) method, which has been established to be suitable for studying the effects of keratin surface damage. Strassburger, J., J. Soc. Cosmet Chem., 36, 61-74 (1985); Joy, M. & Lewis, D.M., Int. J. Cosmet. Sci., 13, 249-261 (1991); Signori, V. and Lewis, D.M., Int. J. Cosmet. Sci., 19, 1-13 (1997)). In particular, these authors have shown that the method is suitable for quantifying the amount of cysteic acid. In general, the oxidation of cystine is thought to be a suitable marker by which to monitor the overall oxidation of the keratinous part of the fiber. Net, the measurement of cysteic acid units by FT-IR is commonly used.

Signori and Lewis (D.M., Int. J. Cosmet. Sci., 19, 1-13 (1997)) have shown that FT-IR using a diamond Attenuated Total Internal Reflection (ATR) cell is a sensitive and reproducible way of measuring the cysteic acid content of single fibers and bundles. Hence, the method that we have employed to measure the cysteic acid content of multiple fiber bundles and full hair switches, is based upon the FTIR diamond cell ATR method employed by Signori and Lewis (1997). The detailed description of the method used for testing the different damage inhibitors follows thereafter:

A Perkin Elmer Spectrum® 1 Fourier Transform Infrared (FTIR) system equipped with a diamond Attenuated Total Internal Reflection (ATR) cell was used to measure the cysteic acid concentration in mammalian or synthetic hair. In this method, hairswitches of various sizes and colors can be used. The switches were platted (−1 plait per cm) in order to minimize variations in surface area of contact between readings. The Oxidative hair Treatment Protocol described above was repeated for 5 cycles to mimic the behavior of hair after repeated bleaching cycles. Following this treatment, four readings per switch were taken (⅓ and ⅔s down the switch on both sides), and an average calculated. Backgrounds were collected every 4 readings, and an ATR cell pressure of 1 N/m was employed. The cell was cleaned with ethanol between each reading, and a contamination check performed using the monitor ratio mode of the instrument. As prescribed by Signori &amp; Lewis in 1997, a normalized double derivative analysis routine was used. The original spectra were initially converted to absorbance, before being normalized to the 1450 cm⁻¹ band (the characteristic and invariant protein CH₂ stretch). This normalized absorbance was then twice derivatised using a 13 point averaging. The value of the 1450 cm⁻¹ normalized 2nd derivative of the absorbance at 1040 cm⁻¹ was taken as the relative concentration of cysteic acid. This figure was multiplied by −1×10⁻⁴ to recast it into suitable units. It was found that virgin mammalian or synthetic hair produced a value of around 20 cysteic acid units, and heavily oxidized hair produced values of around 170. The following instrumental conditions were employed:

Spectral Resolution—4 cm⁻¹ Data Interval—0.7 cm⁻¹ Mirror Scan Speed—0.2 cm s⁻¹

Number of Background Scans—20 Number of Sample Scans—20

Scan Range—4000 cm⁻¹ to 600 cm⁻¹

When the compositions of the current invention can be applied to the hair and then removed there can be a non-significant change to the level of damage to the hair, whereas with conventional oxidative colorants there can be a large increase in the measured damage.

The instant disclosure is not limited in scope by the specific compositions and methods described herein, since these embodiments are intended as illustration of several aspects of the disclosure. Any equivalents are intended to be within the scope of this disclosure. Indeed, various modifications in addition to those shown and described herein can be within the grasp of those with ordinary skill in the art. Such modifications are also intended to fall within the scope of the appended claims.

Color Selection

Also contemplated herein are bicomponent compositions having a given color area (gamut principle described above) defined by color coordinates (a*, b*) in the color space represented by the L*a*b* color system, which can be divided into a plurality of color areas. Each of the plurality of colors obtained from the area surrounding a given set of hair fibers is judged to belong to which color area of the colored area of a certain color. The number of colors judged for each color area is counted, and the color of the color area with the largest number of colors is selected as a representative color of the area surrounding a given set of hair fibers. The compositions are capable of delivering colors on hair (test method herein for fade) such that the results colors lie within the range of about 18<L<about 81, about −2<a<about 45, and about −13<b<about 70.

Also contemplated herein are bicomponent compositions that do not change the hair color, but instead change some other feature of the hair including shine (e.g., making it shinier or matte), the thickness of the hair and/or the feel of the hair.

When the color is removed from the treated material such as hair, the waste water/composition can be treated to remove the pigments from the waste water effluent system. This can be achieved by filtration, or through cyclone technology, where the density differences are used to force the pigments to the settle, and the water to pass through.

EXAMPLES General

The coloring compositions described herein within the example are generally applied to a hair tress, 1 gram of composition per gram of hair, on a flat plate and brushed in to the hair to ensure that all of the strands look visibly coated with the composition. The hair tress is then dried by heating with a hair dryer, while combing until it is dry to the touch and the strands are individualized.

Pretreatment Example

Experiments were carried out to evaluate the contribution of the pretreatment on color uptake and removability using a color composition.

Natural white hair tresses were used. The lower half of the length of the hair tresses were bleached according to a bleach protocol A. The bleached part of the hair tresses show a brightening or color lift.

The prepared hair tresses were subjected to a pretreatment according to a pretreatment protocol given below. After pretreatment, the hair tresses were colored according to a coloring treatment protocol given below. Finally, the colored hair tresses were subjected to an OFF treatment protocol given below.

Pretreatment Protocol

Pretreatment compositions with water as solvent were prepared at given concentrations according to the table below and applied to the hair at a level of 1 ml to each hair tress (about 1 ml per 0.8 g hair). The pretreatment composition was left on the hair tresses for about 5 min before the hair was dried for 30 min in an oven at about 70° C.

Color Treatment

A color composition comprising 5% of film-forming styrene-acrylic resin copolymer (RE-1075 (PMC/SEIKO)) and pigments in a ratio 1:5 of pigment. The color composition is applied to the hair tress, 1 g of composition per g of hair, on a flat plate and brushed in to the hair to ensure that all of the strands look visibly coated with the composition. The hair tress is then dried, while combing with a hair dry until it is dry to the touch and the strands are individualized.

Wash Treatment

The hair tresses were washed for 30 sec with 0.1 g Wella Brillance Shampoo per hair tress and then rinsed for 30 sec. This was repeated 4 times.

Results of Pretreatment Examples

The test results are summarized and discussed below.

indicates data missing or illegible when filed The polyethyleneimine (PEI) pretreatment increases the remanence and shows somewhat satisfactory results for PEI having a weight average molecular weight in the range of about 4 kDa to about 450 kDa, particularly in the range of about 25 kDa and 450 kDa. Even low PEI concentrations are sufficient as the impact on coloring performance remains stable. The hair feeling increase with washing and decreasing molecular weight of the PEI, with low molecular weight PEI of about 25 kDa produces a more natural feeling than PEI having a molecular weight of about 450 kDa. In addition, a hydroxyl functional acrylic polymer combined with PEI was studied for remanence. The coating did not survive five wash cycles. The color removal appears to be better on non-bleached hair. Other suitable cationic polymers are polyallylamine and polyvinylpyridine.
